		/**
 		* PLUGGING INTO USER PAGES
 		* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 		* Userpages are highly programmable and extendable using a number of
 		* hooks. These hooks are:
 		*
 		*   - userpage_sidebar_left
 		*   - userpage_sidebar_right
 		*   - userpage_tabs_links
 		*   - userpage_tabs_body
 		*
 		* You can add a variety of sections to user pages, including new tabs
 		* and new sections on the tables. To add a tab, attach to
 		* userpage_tabs_links and echo out:
 		*
 		*   <li><a href="#tab:YOURTABID">YOUR TAB TEXT</a></li>
 		*
 		* Then hook into userpage_tabs_body and echo out:
 		*
 		*   <div id="tab:YOURTABID">YOUR TAB CONTENT</div>
 		*
 		* The userpage javascript runtime will take care of everything else,
 		* meaning transitions, click events, etc. Currently it's not possible
 		* to add custom click events to tabs, but any DOM-related JS that needs
 		* to run in your tab can be run onload and the effects will be seen when
 		* your tab is clicked. YOURTABID should be lowercase alphanumeric and
 		* have a short prefix so as to assure that it remains specific to your
 		* plugin.
 		*
 		* To hook into the "profile" tab, use userpage_sidebar_{left,right}. Just
 		* echo out table cells as normal. The table on the left (the wide one) has
 		* four columns, and the one on the right has one column.
 		* 
 		* See plugins.php for a guide on creating and attaching to hooks.
